What Is Electric Current?

Electric current is the rate of flow of electric charge through a conductor.

• Definition: (I = ( \frac{Q}{t} )), where (Q) is charge (C) and (t) is time (s).
• Unit: Ampere (A) = one coulomb per second.
• Conventional current: Direction of positive charge flow (opposite to electron motion).
